5000 V digital insulation tester.
In its site-proof casing, the CA 6549 insulation tester offers quantitative and qualitative insulation analysis on a large backlit graphic screen.

Functions and specifications
4 fixed test voltages: 500 / 1,000 / 2,500 and 5,000V.
Adjustable test voltage position: 40 to 5,100V in 10V or 100V increments.
Step voltage mode: R(Utest) measurement curve viewed on the screen and gradient calculated automatically in ppm/V.
DAR, PI and DD quality ratios calculated automatically programmable test length and R(t) measurement curve displayed directly on the screen after measurement with indication of measurement temperature, resistance recalculated at reference temperature for reliable and accurate insulation monitoring.

Many other functions
Test voltage locking, smooth function, programmable alarms, etc.
Storage of several thousand measurements.
USB connector for connection to PC or very compact serial printer.
Power supply: NiMH rechargeable battery for 30 days' operation with 10 DAR measurements and 5 PI measurements per day.
